Hi all!! I just came upon a set of grow light, a 400 watt Mh and 150 watt HPS. Both are sunlight supply and are in working order. OK, where I need is help is where to start. How big should i build the grow box? Ive grown before with out the proper lights with minimal success. I want to start this right and finish with something to be proud of. Please if someone has time, help me a little!!!
